PC220LC-5 PC220-5 Hydraulic Arm Cylinder for Komatsu Excavator Spare Parts 206-63-X2120 Aftermarket High Quality

This heavy-duty aftermarket hydraulic stick cylinder is precision manufactured as a direct OEM replacement for Komatsu PC220-5 standard track and PC220LC-5 long-track medium excavators. As the core hydraulic drive component of front working attachment, it controls arm extension and retraction to complete excavation, rock grabbing, bulk material loading and site leveling tasks. Widely applied in stone quarries, municipal engineering, road construction and medium-scale earthmoving projects.

All cylinders are strictly produced in line with Komatsu original technical standards, with fully consistent mounting dimensions, pin hole spacing and hydraulic port layout. Direct bolt-on installation without cutting, welding or any on-site secondary modification.

1. Dual Model Compatibility

   One cylinder fits both standard-track PC220-5 and long-track PC220LC-5. All assembly sizes, lug spacing and oil port positions fully match original PN 206-63-X2120 cylinder, seamlessly connecting arm linkages and hydraulic pipelines to guarantee stable medium-heavy load continuous operation.

2. Reinforced Medium-Heavy Duty Structure

   Thickened cylinder tube and joint lugs are optimized for quarry and construction harsh working conditions, resisting long-term cyclic loads and accidental rock collision to extend service life greatly.

3. Multi-Round Strict Pre-Delivery Inspection

   Each finished cylinder undergoes repeated full-stroke reciprocating cycle test and high-pressure airtight leak detection, thoroughly eliminating hidden internal and external oil leakage risks.

4. Excellent Cost Performance

   It achieves the same stability and service lifespan as genuine Komatsu OEM spare parts, effectively lowering recurring procurement costs for repair shops, equipment rental fleets and global spare parts wholesalers.

5. Flexible Global Logistics Support

   In-stock goods can be dispatched within 3 working days. Air freight for urgent breakdown orders; sea freight for low-cost bulk wholesale shipments to Africa, Southeast Asia and Middle East markets.
